Frequently Asked Questions
What termination style does the TSM-143-04-TL-DV-P-TR use and how does it affect assembly?
The TSM-143-04-TL-DV-P-TR uses a tail-lead (TL) termination style, meaning the connector has solder tails that pass through or extend below the PCB surface for mechanical anchoring or through-board soldering. This configuration provides stronger mechanical retention compared to flat SMT pads alone, which is important for 86-position connectors at 0.100" (2.54 mm) pitch that may be subjected to mating insertion forces.
How many positions and at what pitch does the TSM-143-04-TL-DV-P-TR provide?
The TSM-143-04-TL-DV-P-TR provides 86 total positions arranged in 2 rows of 43 pins each, with a 0.100" (2.54 mm) pitch between positions. This is the most widely used pitch in through-hole and many SMT connector families, ensuring broad PCB footprint compatibility and ease of layout with standard 2.54 mm grid design rules.
When would a designer select the TSM-143-04-TL-DV-P-TR over the TSM-143-04-F-DV-P-TR?
A designer would select the TSM-143-04-TL-DV-P-TR (tail-lead termination) over the TSM-143-04-F-DV-P-TR (flat termination) when stronger mechanical retention is required, since the tail-lead solder tails anchor the 86-position connector body more securely to the PCB against mating forces. The flat termination variant relies solely on SMT solder pads, while the TL variant provides additional mechanical support through the extended tails, reducing risk of pad delamination under repeated mating cycles.
Is the TSM-143-04-TL-DV-P-TR supplied ready for automated assembly?
Yes. The -TR suffix indicates tape-and-reel packaging, allowing the TSM-143-04-TL-DV-P-TR to be loaded directly into automated SMT pick-and-place equipment. Combined with the surface-mount compatible body and standard 0.100" (2.54 mm) pitch footprint, it supports high-throughput production with standard reflow soldering at peak temperatures of approximately 260°C.
